    Sounds like he used one image, and created three different files from it. I'm just wondering why not just edit the one file. It has all the same data in it. Just seems like a waste of time to me.

    I'm not trying to be mean, I just legitimately don't understand the benefit of doing it this way.

    technically he did edit just one file.

    the information is all there, correct. But you need to gather the information to display it back correctly.

    By creating the three exposures out of the single image, then merging them back using HDR techniques, he was able to unlock the details from the shadows/highlights and then combine it back into one layer.

    Otherwise, just using sliders on the signal raw image may not (or may) garnish the same results.

    Especially just in LR, it's hard to mask out certain areas like just the window in this one, without brining those exposure layers into something like PS.

    Currently I'm fond of using luminosity masks to do something similar. I would create a digital copy in LR with the sky recovered, then bring both images in PS to combine using luminosity masks, then export back to LR.

    something about skinning animals...

    Just sounds like a lot of effort to me. Why not just use the brush tool in Lightroom to bring up/down what you need in the image?

    because LR is an awful program and the brush is not precise enough for most masking work.

    And again, using the sliders may not yield the same results as traditional HDR methods of merging layers and/or tone-mapping.



    I had to export two images out of LR and bring them into PS for this below:

    Imagine trying to accurately mask out the sky area between the pillars and trees in LR. IMHO it would lead to sub-par results and obvious haloing.

    this was the mask I used:

    Plus PS did a stellar job removing the people scattered through compared to LR's performance-killing spot "tool".

    A somewhat simpler method is to make three exposure levels from a raw image, and then blend them as layers. Not quite as controlled, but it often works.

    I need to try that. A lot of people whose work I admire have recommended it.

    I have many times taken images of airplanes flying where only a single image is possible and using photoshop will change exposure values + and - 1 step apart giving me the multiple images needed for a good hdr in photomatix with very good results b17 hdr.jpg

    I love what good HDR can do for machinery.
